“…The number of laser beams using for the LIL strongly affects the morphology of surface patterning. Thus, three- [122], four- [123], and even six-laser beam [124] LIL processing have been developed. Wang et al modulated the intensity distribution by using a spatial light modulator (SLM) and realized complicated surface patternings similar to the laser intensity distribution [125].…”

As a noncontact strategy with flexible tools and high efficiency, laser precision engineering is a significant advanced processing way for high-quality micro-/nanostructure fabrication, especially to achieve novel functional photoelectric structures and devices. For the microscale creation, several femtosecond laser fabrication methods, including multiphoton absorption, laser-induced plasma-assisted ablation, and incubation effect have been developed. Meanwhile, the femtosecond laser can be combined with microlens arrays and interference lithography techniques to achieve the structures in submicron scales. Down to nanoscale feature sizes, advanced processing strategies, such as near-field scanning optical microscope, atomic force microscope, and microsphere, are applied in femtosecond laser processing and the minimum nanostructure creation has been pushed down to ~25 nm due to near-field effect. The most fascinating femtosecond laser precision engineering is the possibility of large-area, high-throughput, and far-field nanofabrication. In combination with special strategies, including dual femtosecond laser beam irradiation, ~15 nm nanostructuring can be achieved directly on silicon surfaces in far field and in ambient air. The challenges and perspectives in the femtosecond laser precision engineering are also discussed.

“…[2] Such a combination introduces the non-wettable phenomenon to any desired surfaces like glass, metal, wood, paper, fabrics, etc. Owing to this inspirational phenomenon, different research methods have been developed to create a robust non-wettable superhydrophobic surface such as spin coating, [3] spray coating, [4] imprinting, [5] templating, [6] lithography, [7] plasma treatment, [8] chemical vapor deposition, [9] electrospinning, [10] etc., during the past few decades. Tu et al, [11] developed the SH surface by spraying perfluoroalkyl methacrylic copolymer (PMC) suspended with TiO2 nanoparticles (Nps) over polydimethylsiloxane precoated wood substrate, in that the TiO2 Nps impart the essential roughness while the PMC provides LSE and binds the Nps together providing a robust coating.…”

Surface frictional drag developed by marine vessels utilizes a considerable percentage of fuel for propulsion. Superhydrophobic (SH) surface normally traps a layer of air at the interface and significantly reduces the surface frictional drag. Herein, the efficacy of the SH coating towards the surface drag reduction of the sailing boat is recognized by conducting a facile experiment where the bottom of the toy boat is coated with SH additives. AlNiCo nanoparticles and nickel stearate prepared by ball-milling and co-precipitation methods respectively are drop-casted layer by layer over the surface of the toy boat to impart SH. The fuel efficiency of the SH boat is improved by 51.49% substantiating the reduction in surface drag of the vessel. Further, the trapped air provides extra buoyancy force, enhancing the load-bearing capability of the SH boat by 5.77%.

“…Through years of effort, studies have demonstrated that a micro/nanoscale rough structure and low surface energy are two key factors in obtaining a superhydrophobic surface. Techniques to fabricate superhydrophobic surfaces have also been developed, such as templating, nanoimprint lithography, the sol–gel technique, − electrochemical deposition, , layer-by-layer assembly, , and chemical etching method. However, the impediment to fabricating artificial superhydrophobic surfaces is that they can easily loose their functions when exposed to harsh mechanical conditions. , The micro/nanoscale structure, which is significant for maintaining the superhydrophobic property is highly susceptible to mechanical wear by even a slight finger touch.…”

Superhydrophobic coatings have received considerable attention owing to their potential applications. There has been an increasing demand for the construction of durable superhydrophobic coatings using cost-effective and fluorine-free chemicals. Herein, we developed a simple, universal, and eco-friendly approach to fabricate durable superhydrophobic coatings. The as-prepared coating was composed of synthesized fluorine-free hexadecyltrimethoxysilane-modified SiO2 nanoparticle-coated halloysite nanotubes (HDTMS-HNTs/SiO2) and a commercial water-based silicone–acrylic emulsion. SiO2 nanoparticles covered the surface of the HNTs to create a hierarchical micro/nanoscale structure. The silicone–acrylic emulsion bonded the HDTMS-HNTs/SiO2 nanoparticles and anchored them onto the substrate. The as-prepared superhydrophobic coatings exhibited high performance, including a water-repellent property and outstanding mechanical durability. The coatings maintained superhydrophobicity after tests for sand impact abrasion, 50 cycles of sandpaper abrasion, finger touch, and 30 cycles of tape-peeling. Additionally, the simple spray-coating method at room temperature also made the coatings substrate independent, making practical application of superhydrophobic coatings in real life more feasible.
